SUMMER-FR ON T GAS-G RATE.

SPECIFICATION forming part of Letters Patent No. 650,137, dated May 22,- loco. Application filed December 12, 1898: Serial No. 699,044. (Nomodel.)

To on whom it may concerm',

Be it known that I, GEORGE E. SHARPE, a citizen of the United States,residing at Steubenville, in the county of Jefferson and State of Ohio,have invented certain new anduseful Improvements in Summer-Front Gas-Grates, of which the following is a specification.

My present invention relates to improvements in gas grates or stoves,and has particular reference to that class which is prima" rily designedto be placed in open fireplaces.

The principal object of this invention is to provide a gas-grate in theform of a combined burner and summer-front which may be readily adaptedto close any ordinary fireplace with frames having square openings orcircular tops and which will safeguard against contact of dresses orother movable objects with the flame. j

A summer-front, as is well known, besides its other functions isdesigned to hide the coal-grate from view at certain seasons of theyear. In addition to these my invention presents the advantages of agas-grate which may be used in place of the hidden coal-grate at timeswhen the temperature of the apartment is low enough to necessitate someheat.

With these and other objects and advantages in View the inventionconsists of certain novel and useful combinations and arrangements ofparts,"whichare clearly described in the following specification, andparticularly pointed out in the claims forming a part hereof.

In the drawings annexed hereto and forming a part of the specification,Figure 1 is a front elevation of my improved gas-grate constructed as aburner and summer-front with the front plate removed. Fig. 2 is aremovable front plate used to close the front of the gas-grate. Fig. 3is a rear elevation of Fig. 1 with parts broken away. Fig. e is atransverse sectional view on the line 4 40f Fig. 3. Fig. 5 is a verticalsectional view on the line 5 5 of Fig. 1. Fig. 6 is a perspective viewof the gas-grate proper with certain parts broken away to more clearlyshow the construction. Fig. 7 is a transverse sectional view on the line7 7 of Fig. 6, the perforated plate of the gas-grate being removed. Fig.8 is a rear perspective view of the gas-grate, showing a strip or platewhich may be secured to the top thereof where the combined gas-grate andsummer-front are inserted in a fireplace having an upper projectinghood. Fig. 9 shows a modified form of gas-grate and summerfront designedfor use in fireplaces having frames with circular tops. Fig. 10 is adetail view of the strip or plate which may be attached to the top ofthe gasgrate or summar-front.

Like letters of reference denote like parts throughout the severalfigures of the drawings.

- A'represents the frame usually surrounding the fireplaces ofcoal-grates, and, as shown in Figs. 1 and 9, they may be eitherrectangular or curvilinear. In the practice of my invention I may secureor form on these frames, integral therewith and at suitable intervals,the lugs or keepers a to retain the summer front and gas grate inposition.

These lugs occur on the rear edges of the frame-opening. 13 represents aplate or casting having the functions of a summer-front, and formedtherein is an opening I), which may be of any preferred shape, but whichis here shown as rectangular. At the top and overhanging this opening isa hood I), which extends across from side to side. At the foot of thissummer-front plate is a removable door N, which permits access 'to'thevalve E and certain other parts of the gas grate or stove, to bedescribed farther on. As is obvious, this summer-front plate B maybeornamental or plain. At each lower corner of the rectangular opening bis formed a keeper b These keepers are designed to retain in place aremovable front plate W. This plate closes the front of the summer-frontplate and may be plain or of open-work and maybe 0rnamented in any styleto enhance the beauty of the summer-front. c

As the openings of all fireplaces are not of equal size,but may Varyseveral inches, I have provided means for adapting my summerfrontgas-grate to any size or shape offopening. casting'B and on the frontface thereof the adjustable wings B B. These wings are slotted atsuitable distances from the top and bottom, as at b b, and through theseslots extend the pins or studs 11 which are secured Isecure on each sideof the plate or 5 justment of the wings B to close the-open ings ateither side of-the summer-front plate B, where it is notas wide as thatof the tire; place-opening. To close any opening at the top, I provide aplate B secured to the top of the summenfront plate by bolt and nutpassing through a vertical slot b to permit vertical adjustment, andsecured to this plate by bolts andnuts passing through horiZontaF slots11 are extension-plates B These extem 15 tension-plates, where they meetcentrally, are a a sort of slot conformingto cut away to form slott'finthe plateB A 'Ifotherearffacejof the summer-front plate B. may besecured yb or conn c ed in any eenvenient manner the gas grate or stoveproper. Thisigas grate or stove. maybe of any suitable construction, orit may be as .sho in thefdrawings. As, there illustrated it consists ofa pan-shaped plate 0, formed,

preferably, of one piece of seamless sheet,

metal, the top and sides of which areproded with. flanges. by Which'thepan maybe.

tweenthe perforations in the plate 0 which 6o areleft exposed and arehere shown in par-. 1

allel, lines, I coat the surface with asbestos.

Inter-posed between the gas-grate and the summer-front plate B andcovering the opening in the latter is a sheet or web of foraminousrnaterial G, preferably woven wire of fine mesh. This foraminous webserves to prevent the escape into the room of gas or noxious odorsarising from the burning gas, and aside from this its principal objectit serves as a guard to prevent dresses or other moving objects fromcoming into contact with the flame. B'yconstruct ingthebody of thegas-grate as shown with the reservoir pressed therefrom no gas canpossibly escape fromthebaek of the same. web between the gas-grate.andthe opening of the summer-front plate. none canle'scape through thatsource into, the. room. Oon'se-.

In Fig. 9 I have shown a modified fo rin of construction whereby asummer-front g asgrate is adaptable to..fireplace s Qhavingfa.

In-Figs. Sand 10 I have shown apla'te H, which may be used where thefireplace=firanje is formed with an overhanginghood, such as shown. atH, dotted lines, in Fig. 5.; This iplateiscut with a curved edge, asshown,

and has the downturned flange, h, by. which it is secured upon the topof the gas-grate. The vertical. slot h. is formed therein. centrally tofit. over the. bolt, which. secures-the upper adjustable plateonwing Bi,The fiange of this plate H may be. inserted between the plate and the.washer on the. boltandthereliy clamped in place.

L This completes the construction of my invention, and its operationwill be readily .understood from the foregoing description without.further explanation.

I do. not desire to limit myself to the pre' cise details ofconstruction herein. shown and described nor to the exact arrangement.or location of parts, but reserve. to myselffthe right'and privilege toalter the. samewithin the. .boundsof mechanical skill without departingfrom the spirit. of my invention.

( Havingthus fully described .inyrinvention, what I claim as new, anddesire to secure. by Letters Patentof the United States, is}

p 1. The. combination with a fireplace-frame havingon its rear faceupper and lower opposing lugs or keepers, of a burner and summer-frontprovided with laterally-adj ustable side extensions or wings which; restorabut against said lugs or keepers, and a top extension for said burnerand summer-front which is both laterally and vertically adjustable andprojects upwardly behind the fireplace-frame, substantially as describedand set forth.

2. The combination with a fireplace-frame having on its rear face upperand lower opposing lugs 0r keepers, of a a combined burner andsummer-front provided with adjustable side extensions or wings whichrest or abut against said lugs, a top extension for said summer-frontwhich is both laterally and vertically adjustable and projects upwardlybehind the fireplace-frame, as and for the pur poses described.
